In the past when sideboarding for the control matchup, you couldn't grab your copies of Chrome Mox fast enough. It made sense for that time, you wanted to be on a more consistent game-plan with more resiliency – this is where the "Grinding-Station" theory came from. That said, this plan is out-dated in today's metagame. With the addition of Accumulated Knowledge, the control decks have such a strong late game as they create actual card advantage instead of theoretical card advantage with Sensei's Divining Top. This creates situations where even multiple copies of Past in Flames isn't effective against their flurry of Flusterstorm, Surgical Extraction, Force of Will, and Snapcaster Mage.
Well, how do we beat that?
By going under them! This is where our good friend Chrome Mox comes back to the equation. These control decks are actually weakest in the set-up stage of the game, meaning that fast hands with a single piece of disruption are generally good enough to defeat these menacing control decks. Other than Accumulated Knowledge, there's also Counterbalance out of Miracles and Hymn to Tourach out of the black-based control decks.
An easy and effective way of playing around these cards is to simply combo off before they're relevant. With Hymn to Tourach based control decks, one strategy I personally like is playing out my artifact mana (Chrome Mox, Lotus Petal, and Lion's Eye Diamond) and then allowing the Hymn to Tourach happen. TES is a very threat based deck with typically 7-8 "tutor effects" to draw off the top of your library, allowing a lot of "I win the game" scenarios.
When sideboarding you should think of how your opponents are trying to combat you, for these matchups, all types of control decks are bringing in copies of Flusterstorm, Surgical Extraction, and Pyroblast. This is manageable, you can combat Surgical Extraction rather easily as it's not actually that good against TES (we don't really utilize Past in Flames as much as Ad Nauseam Tendrils). What you could do is sideboard in your copy of Tendrils of Agony because if the control player hits a copy of Burning Wish (with Surgical Extraction) that will leave you with Empty the Warrens as your win condition. This is an issue because Empty the Warrens isn't typically the strongest in these matchups due to cards like Terminus, Batterskull, Toxic Deluge and Marsh Casualties.
The next card to fend off would be Flusterstorm, which isn't always the easiest. Against the blue & white based control decks, cards like Xantid Swarm, Hope of Ghirapur, or even Defense Grid are very effective against this, but if you don't like these cards you can always attempt to overload on discard spells. I'm personally not a big fan of going over seven to eight discard spells as you're only fighting them on one axis while they're combating you on several (the stack, graveyard, and permanents). In theory, discard spells can answer all of these, but in actual game play cards like Brainstorm or Snapcaster Mage can hide cards long enough to defeat you at an opportune time. Something like Xantid Swarm, Hope of Ghirapur, and Defense Grid can't be targeted by Flusterstorm which will create a huge impact on the game. These strategies only work agains the blue & white based control decks, against the Hymn to Tourach based control decks I don't think permanent based answers that stop counterspells are effective. When the opponent has a solid mixture of discard spells and counterspells, it makes these strategies rather embarrassing. Not to mention the fact all three cards are answered by Kolaghan's Command.
The last way to fight against these decks (blue & white based control) is to bring in answers for permanents, it doesn't matter if you're splashing green for Abrupt Decay or staying Grixis. You should bring in some sort of answer for Counterbalance, Ethersworn Canonist, and the uncommon Meddling Mage. Against the Hymn to Tourach based control decks, if they play more than two copies of Leovold, Emissary of Trest I try to sideboard in a few answers as I don't want to be forced into an Empty the Warrens line if the situation doesn't call for one. If you don't understand why, please read the "Small Creature Combo" decks section for the answer.
Recently, I've written an article on how to "combat Miracles." to give you an abbreviated version of the article, if you want to beat them you need to do it early. Because of this, you should keep Empty the Warrens in your deck as it's the easiest way to combo off quickly. Pairing this strategy with Hope of Ghirapur is my preferred way of winning this match-up.
